报告摘要：

Helium nanodroplets provide a unique environment for trapping molecular species and thus open new possibilities for the study of physical and chemical phenomena. Characterization of these nanoreactors important aspect for a better control of the embedded species. In this context, we have studied the Interatomic Coulombic Decay (ICD) process in helium nanodroplets.

In the talk, I will discuss what is ICD and how it can be triggered in helium nanodroplets, I will then report on a recent experimental and theoretical study of the timescale of ICD in resonantly excited helium nanodroplets using free-electron lasers.

Dr. Prof. Nicolas Sisourat, Laboratoire de Chimie Physique - Matière et Rayonnement, Sorbonne Université, Paris, France. He is a highly accomplished researcher in atomic and molecular physics, theoretical chemistry, and computational physics. The main research activity is the development of theoretical approaches and associated numerical tools for the description of ultrafast electronic and nuclear processes, including the electronic motion in the course of electron- and ion-molecule collisions, the electronic and nuclear response of a molecule in an intense laser field and the electronic decay processes of excited molecules and the nuclear dynamics associated to it. He has over 80 publications including in high-ranked journals such as Nature Phys., Nature Chem., Nature Comm., Phys. Rev. Lett. and J. Phys. Chem. Lett., etc. He also serves as referee to these journals and in editorial capacities.
